I think Yuvraj should not engage in such drama. In real time it did appear he had nicked the ball. There was noise and deviation. The umpire was in no doubt and that is why did not give the benefit of doubt. I think Yuvraj tried to act oversmart because it was an Indian umpire had it been non-asian he would dare not. Lately I think the umpiring has improved tremdously and we should all applaud that. Infact 95% of the times you have even commentators saying "ohh that is close - that should be out" and then after taking a look at the Slow motion - say " wow the umpire has got it right - that was a great decision" Of course you will have few that go the wrong way but that is the human element in the game which makes is so much more interesting and unpredictable. Even in football you will see refrees at times getting it wrong and showing yellow card to the player and if he does dispute a red card is at refrees disposal. Yuvraj in his career I am sure must have got the benefit even when he must have been out. What has he done at such times - walked away saying he was out - no smirking and carried on.
